An informant disclosed to Business Insider that Styles and Swift began a holiday in the British Virgin Islands last week, but got into a heated argument that led them to end their romance.

Swift apparently left the Islands following the split, while Styles stayed behind to attend a party on Richard Branson's Necker Island.

"Richard Branson heard Harry was staying nearby so invited him to come check out Necker," an insider told the publication. "So when Taylor left for the States, Harry went to Branson's island for the day to let off some steam."

The source continued: "[Harry] did plenty of partying and was definitely enjoying himself while hanging out with guests. He returned to Virgin Gorda in the early morning hours looking like he had a raucous night."
